I don't know how many times I have sanded the edges of my wheel well sheet metal, painted with POR15 and then overcoated with matching body paint on outside edge.

But each year, the rust comes back. It seems that the edge of the metal doesn't get properly coated even although I have slathered on the POR. No problem on the inside, probably because it is easier to build up some POR thickness.

Anyone Have any better ideas?
